Such a shindy is too hot to last, and, accordingly, if you're alive at the end of two jiffies, the chance is that you find yourself making quite a melodramatic Tableau—namely, your bloody sword in one hand, a Chinese pigtail in the other, and four or five weltering Tartars lying round your feet!

- Old Applegate, in the stern, just set and looked at me, and Lord James, amidship, waved both arms and kept hollering for help. I took a couple of everlasting big strokes and managed to grab hold of the skiff's rail, close to the stern. Then, for a jiffy, I hung on and fought for breath.

- The FOR...NEXT loop for TIME increments by STEP 2 (every two jiffies) for two reasons: 1) the printing of 60 jiffies a second is too fast to read, and 2) the printing of each jiffy takes longer than its incrementations; this would delay the loop, so the printing of TIME$ is slower than it should be.
